Every second inside every living cell, thousands of chemical reactions are taking place. These reactions constitute the essential tasks of life such as metabolism, protein synthesis, cell renewal and growth. Learn how the proteins called enzymes work to maintain the rate of these reactions at a life-sustaining level.
Based on atomic structures from the PDB archive, observe the mechanism of aconitase, an enzyme of the citric acid cycle, to understand how enzymes utilize their amino acid residues to catalyze a reaction.
To learn more about enzymes, explore the educational resources on PDB-101 (http://pdb101.rcsb.org/browse/enzymes).

nice information… another must read https://www.scienceofhealthy.com/enzyme-catalysis/
How did the animation made?
Most underrate vid. I've ever seen
Superb video with amazing animation. Absolutely stunning that our DNA codes for such a vast array of protein structures. Thank you for sharing.
Great explanation on what enzymes are and how they assist in the chemical reaction process. Thanks a lot.
Can really see how close life and non-life are, almost like one of those magic stories like Harriet's Hare, where some animals have Consciousness and the ability to talk and others don't.
It's very difficult even in pure chemistry to regenerate catalysts. How our body does it.
This is great, but I wonder what it might be like if this process was explained via a more mechanical method… like a robot holding products and changing them. Proteins are proteins, but learning steps through easy to envision mechanical processes seems like it might help. Just a thought.
Can enzymes be used to make battery power
This was really cool. Very clear and great and understandable animations. More people need to see stuff like this to understand the absurdity of these vastly complex systems originating by random processes.
This an excellent animation… but the video itself is a little off in terms of scope. The intro and final statements are in the format of something you would show to children… but the contents are complex enough that it totally clashes with this format. If you are familiar with ANY of those reactions, then you already know what enzymes are… And if you don't know what enzymes are, you are going to be totally lost after 30 seconds. It is still good content though, even if the delivery is a little… wooden.
Wowww very superb video. Love love
great animation Maria Voigt!
So great, how did people figure this out jeez..
wawww
What causes the cis-aconitate intermediate to flip upside-down?
Enzymes, the bodies Energizer Bunnies on steroids! Lol!
Thanks you for your video is very helpful for students (like me)
Show this video in biochemistry 101… And people will understand enzymes much better
Thanks!
Subhanallah that is amazing
This is really good.
Bundle of thanks my sweetheart angel KD 😘

After watching this video, one has either to be a convinced atheist or a true believer; there is no middle ground.
vitamins co enzymes?
I now remember why I switched from biochemistry and decided to focus on inorganic chemistry.
Incredible. The physics of molecular biology, the complexity of evolution, the ingenuity of biologists to have worked all this out, the quality and accuracy of the computer model, the generosity of the uploader; all very impressive.
A molecular assembly plant. I want to make an enzyme that will turn lead into gold.
Wow that's cool thanks for sharing, I never knew it worked quite like that!
From what i understand, those reactions really do make those popping sounds.
Vietnamese please
Sounds like Morpheus.
My pie hole eats burger. My tummy makes it into mush. My colon sucks up sub microcrosic elements. My @hle makes a brown curly wurly next day. I am happy.
I needed this
Thank you!
Wow! That's awesome! Thank you. 😃😄😊
I'm brand new to biology, please explain how this information is knowable if its so small and happening so fast. Is it filmed under an electron microscope then slowed down?
How they know this work this way it a real human
God is an enzyme in disguise.
